If you are looking for a cost-effective and durable single-ply roofing system for your flat or low-slope roof, a TPO (thermoplastic olefin) membrane may be a solid, energy-efficient option.
A typical residential TPO roof will cost between $7.50 and $14.50 per sq. ft. installed. Thus, for an average-sized 1,200 sq. ft. flat roof, your total cost to install a new TPO roof can range from $9,000 to $17,400, depending on the project specific variables, contractor choice, and your home’s location.
The above cost assumes a low-slope roof on a single-story or two-story house, the cost of materials and supplies, removal, and disposal of up-to one layer of existing material such as EPDM rubber, permitting, installation, and a 5-year workmanship warranty.
Note: the cost can be significantly higher in expensive metro areas and on complex flat roofs that involve additional work and/or are difficult to access.

Did you know? TPO membrane can provide combined benefits of both, EPDM rubber and PVC roofs, but at a more economical cost than PVC.
It’s therefore not surprising that TPO roofing systems are quickly growing in popularity and demand, in both residential and commercial flat roof markets.
TPO in a Nutshell
A TPO membrane is made from ethylene propylene rubber. Special technology is used to chemically bind together, rubber, ethylene (an organic gaseous substance) and propylene (a byproduct of petroleum refining). At the end, numerous filler materials are added, such as talc, carbon filler and fiberglass. — These fillers reinforce the TPO membrane’s strength and durability.
Did you know? TPO roofing membrane has been specifically designed to have the advantages of a rubber roof, combined with hot air-weldable seams for extra durability.
TPO membranes have been manufactured in the US since the early 1990’s and are now the fastest growing segment of the US single-ply roofing industry.
TPO Membrane Options
TPO roofs are manufactured to meet a variety of needs and design specifications. They are available in white, light gray, and black colors. White TPO roofs offer the best solar radiant heat reflection properties, hence they are the most popular choice thanks to their energy-saving potential.
For most residential applications, TPO membranes come in two thicknesses options: 45 mils (.045″) or 60 mils (.060″). The width and length of the membrane can vary depending on the manufacturer, with a typical TPO membrane roll being 6 to 6.5 ft. wide and 100 ft. long.
Other membrane thicknesses and widths are also available depending on the manufacturer, including a 3 feet-wide rolls for the edges of the roof. Commercial grade TPO membranes may have a thickness of up to 80 mils (.080″) and may come in up to 12 feet-wide rolls.
